TO ALL WHOM'ITl hIAYCONf/ERN l e it known that I, HENRY ROBES, of Clarence Centre, in the county of Erie, and State of New York, have inventeda certain new and useful Improvement in Combined CornJlanters and Plaster-Droppers; and I ilo-hereby declare that the following is a full and. exact description thereof, reference being had to the accon1- panying drawings, making` part of this specification.

Figure 1 is a'plan ofmy improvedl machine. Figure 2, a verticallongitudinal section;r

My inventionV consists vessentially intheY combination of a corn-planter and plaster-dropper, having the dropping apparatus of each so'connccted as to open the one and closethe other simultaneously; also in the special arrangement of thc dropping apparatus; also in the employment of a gauge-slide in combinatioil with the plaster-slide for measuring the amount of plaster dropped at once,V also in the arrangement of parts for raising and lowering the drill-tooth andl coverer; also inthe employment of'an adjusting gauge and elastic -connection in combination with the hinged plaster-discharge tube for directing the plasterA in the tube; and finally, in the general arrangement of the machine.

Asrepresented in the drawings, A isla main frame of suitable construction, and B B the driving-wheels; this fraude, at suitable-distances apar-genden oppcsi'tesides, are mountedv'the born hoppers C Gand plaster'- ioppers D D. Across'theframe ata suitable position is situated a rock-shaft, E, that receives motion bymeans :t of a roller, aon"its crank end b coming in 'contact with a triangular-shaped cam, c, which is fast' tothe driving- "wheeL The reaction-'ot' the shaft to produce the rocking motion i's accomplished by a spring', d, iig. 1,-wound ,riiiind the shaft, or by sou-ie equivalent means. In line with the hoppers the shaft is provided at each end with -a stii arm, f, which operates the dropping arrangement connected with the corn ant'. plaster-hopper. This arrangement consists of slides F and G, connected at g g to the armand resting respectively under'the hoppers. 'The corn-slide F Ais simply a straight bar having a; seed-cavity, h, whose capacity is'measured by ,a gauge, t', l moved up or back, and fixed in any desired position by a set-screiv`, as shown inI fig. 3. A brush, k, is situated 1 lin *thel hopper in such position as to prevent undue escape of the corn. At each reciprocation tho'corn in cavity is dischargedl in jointed tube j. 'The slide Gr which rests `under the plaster-hopper has two plates, l l', sepa-- rated vertically such a distance as to measure the required quantity of' plaster, and so situated, one past the other, that when one is under the' outlet of the hopper the other isremoved clear therefrom, and vice versa. In aotionvit will be perceived that these plates will cut off and drop the required amount of plaster each time into i the discharge-tube without allowing undue escape. It will also be noticed that when one hopper drops the other is closed, andjvicc versa. I In order to gauge or mea-sure the desired amount of plaster a plug, n, is made to slide in more or less beneath the hopper D, as shown in dg. 3. lThis plug is preferably connected with a lever, o, fig. I, Vso that'the operator can regulate the quantity of plaster dropped while going over the field, and without stopping the machine. By the employment 'of this arrangemeent of the dropping-slides in combination with the' hoppers C D, it-will be seen that both corn and plaster can be dropped at one and the same operation, the cornbein-g first dropped and covered, and the plaster then dropping directly upon the hill. To accomplish this the movement of said slides is perfect, the one o'pcningwhen the other is closed. This automatic action is necessary to accomplish the desired purpose, and the double action is so simple and unfailing that the plaster can be dropped upon the hill much more accurately than could be done by hand. I am not aware that a coml bined corn and plaster-dropper has ever before been known in which the dropping-slides have been arranged as a whole, with one movement, and in which the corn is rtt dropped' and covered and the plaster then dropped uponnthc hill. In connection with the slidefplates l Z of the plaster-dropper the gauging-plug u is of the utmost importance, for it enables nie'to drop a large or' a smaly quantity, as desired. In frontof roch-shaft E is another, H, and at each endV of this is a still arm, p, having a series of adjusting-holes, g g, in its lehd,'t`or the 'attachment of a stirrup or.clevis,/r, g.'2.. This stirru'p'encloses a draw-bar, I,jointed to the front of the frame at s, and lholding at its rear the hollow'drilLtoot-h t which adjusts up and down over thejointed .corn-whey.

The piVotof stixfrup r holdsv a-friction-roller, for pressingdown thevbar'I with as little friction as possible.

. l-Anoth'er double droht-bar, I', fisnlso joint d ats, and extendingback, holds the coverer o which covers the drill'.

This co'verer is made concave or hollowin'g. on the under side, as shown, so as to concentrate the soil over the.

drillandround and smooth it'oif-properly.v The rear ends of drow-barsll are 'connected by a flexible l connection, zo, as showin. Itn'ill be perceived that by turning the arm p downward, as in iig, 2, the roller u 'will force the draw-basl down. and hold it in' position to retain thedril'l-tooth t in the soil. At the same time the'ilexible connection@ allows'thocojerer to driig'over the drill and cover. it, as before described. This con- 'nectionfiso'f mich 'i-niportanee, -feifit' allows a freeand independent oction of both the drill-tooth 4and the coverer.' ,In-going overineqn'alities, with the tooth in advance, of course itis necessary .that the tooth should rise 4 and-fell vWithout thecoverer. At the same time that this 4eectis accomplished both the drill-toothnnd tbe 1 oo verer will be iaisedfrotntho ground by the single action 'of the arm The rock-shaft H is operated by a lever, K, A attache d thereto, moving overl a. quadrant, L, and' secured in any? desired position by adjusting-holes fsitnatedt-therein. Theif'oclreshsi'ts E H hav-e 'arms yconnec-ted by a chain or cord, Z, 4b'y which means the V"roller-agis l.tlrrovitri array from camcto disengage the same. The-plastentubent is hn-ngor pivoted at e, so as tol swing freely. 'l 'Ithasattaohed to its front 4side an elos'tiocord, a', which draws it forwntljagainst an adjustinggange,-, b, set forward or back a set-screw. `:By thi'sf uieansit will lbe ssen that the angle or position of the said tube I nsyrbeadjustedy forward or back exactlyas re'qixired 'to adapt itto direct the plaster directly upon 'th'e'planted 'h ill.4 This crrangementis of `much importance, for Ait enables the plaster to be'dropped accurately,

' no matter what may be'the distance of the hills or the condition of the soil. A shaft, M, extends tbroughboth plester-hoppers, armedspirally .with pins or teeth c c vrhich properly agitate'thc plaster above the discharge I -openings of the hoppers, This shaft is driven b'y a. band, fl, passing over pulleys ff 'What I claim as my invention, 'and desire tmsecure byy Letters Patent, is- 1 2l.` The combination, with' a corn-p l-aiiter,-0, and 'plasterdropper D, of a dropping arrangement that by s :single m'oi'ementj shallopen lthe one and close the other automatically, and vz'ce versa, as herein set fprtli."
